Inventor: SHIBATA AKIRA
IPC: F16F13/18
Filed: 1994-11-24
Abstract: PURPOSE: To provide an engine mount which shuts off engine vibrations to be transmitted to a car body in good performance and allows easy air bleeding operation at the time of installation. CONSTITUTION: A main liquid chamber 51 is separated from an aux. liquid chamber 52 by a partition plate 53.
